Then, join all the three leads together with tape. Apply two more layers. Slip back the PVC
pipe and the cap over the joint in such a way that it covers the joints equally. Retain it in the
same position using PVC tape and put the rubber compound over the cap.
Keep the PVC pipe vertically for pouring the hot compound. Melt the hot film compound
and pour in to the PVC pipe till it is filled. keep the cable at teh centre while pouring the hot
compound. Place the other rubber cap and apply the rubber compound.
COUPLING
NEMA standard splined shaft extension is
provided for easy coupling. This will ensure
prolonged spline life of the coupling and mo-
tor. It also prevents abrasives entering from
the well into the spline area. Before coupling,
check that the mounting faces of pump and
motor are free from dirt and dust.
WARNING !
Before coupling, ensure the mounting areas
of pump and motor are free from dirt and
dust. Align the pump coupling with motor
shaft and slide on it. Then tighten the as-
sembly nuts / studs equally and firmly com-
plying with tightening torques specified by
the manufacturer.
WARNING !
An adequate flow of cooling water is man-
datory to avoid overheating.
Motor should be lifted from stud portion of upper housing through chain pulley block /
other lifting equipment during erection. Erect the tripod and fix the chain block in such
a way that the hook of the chain is positioned exactly above the centre of the bore well.
Unscrew the strainer and cable guard. Using the megger, check the insulation resistance
of the motor. Place the motor vertically near the bore well.
Take out the pump the package and check the rotation of the pump shaft. Apply the
threading compound to the threaded portion of the pump and the short length pipe.
Screw up the short lenght pipe in to the pump (ensure taht the threaded length of the
short length pipe and delivery pipe and suspend the pump using the chain block.
Clean the motor seating surface and the pump seating surface before the motor and the
pump lift and lower the pump carefully on the motor while doing so ensure three things
1. The pump shaft must be inserted in to coupling.
2. The studs on the motor must be passing through the suction housing holes.
3. The cable coming out of the motor should passing through the slots provided in the
suction housing.
After coupling the pump set on the motor, tighten all the nuts uniformly and frimly. Check
the axial movement and free rotation of the motor and the pump shaft assembly with the
help of screw driver placing it in the groove provided in the coupling. Fit the cable guard
and strainer properly.
